2. Gain (electronics) - Wikipedia

   en.wikipedia.org/wiki/Gain_(electronics)

   The term gain alone is ambiguous, and can refer to the ratio of output to input voltage (voltage gain), current (current gain) or electric power (power gain). [4] In the field of audio and general purpose amplifiers, especially operational amplifiers , the term usually refers to voltage gain, [ 2 ] but in radio frequency amplifiers it usually ...

3. Bridged and paralleled amplifiers - Wikipedia

   en.wikipedia.org/wiki/Bridged_and_paralleled...

   A bridge-parallel amplifier topology is a hierarchical combination of the bridged and paralleled amplifier topologies, with at least four single-ended channels needed to produce one bridge-parallel channel. The two topologies complement each other in that the bridging allows for higher voltage output and the paralleling provides the current ...

5. Power-added efficiency - Wikipedia

   en.wikipedia.org/wiki/Power-added_efficiency

   Power-added efficiency. Power-added efficiency (PAE) is a metric for rating the efficiency of a power amplifier that takes into account the effect of the gain of the amplifier. It is calculated (in percent) as: It differs from most power efficiency descriptions calculated (in percent) as: PAE will be very similar to efficiency when the gain of ...

6. Amplifier figures of merit - Wikipedia

   en.wikipedia.org/wiki/Amplifier_figures_of_merit

   The gain of a good quality full-range audio amplifier will be essentially flat between 20 Hz to about 20 kHz (the range of normal human hearing). In ultra-high-fidelity amplifier design, the amplifier's frequency response should extend considerably beyond this (one or more octaves either side) and might have −3 dB points < 10 Hz and > 65 kHz.

8. Low-noise amplifier - Wikipedia

   en.wikipedia.org/wiki/Low-noise_amplifier

   Low-noise amplifier. A low-noise amplifier ( LNA) is an electronic component that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio (SNR). Any electronic amplifier will increase the power of both the signal and the noise present at its input, but the amplifier will also introduce some additional noise.

9. Programmable-gain amplifier - Wikipedia

   en.wikipedia.org/wiki/Programmable-gain_amplifier

   A programmable-gain amplifier ( PGA) is an electronic amplifier (typically based on an operational amplifier) whose gain can be controlled by external digital or analog signals. The gain can be set from less than 1 V/V to over 100 V/V. [ 1] Examples for the external digital signals can be SPI, I²C while the latest PGAs can also be programmed ...
